## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | K | passive | Cathode (-) of the LED, marked by the cathode mark on the package; reverse voltage VR max 5 V (IR test condition only, not designed for reverse operation). |
| 2 | A | passive | Anode (+) of the AlGaInP brilliant red LED; forward current IF max 25 mA, typical VF 2.0 V at IF=20mA, use a series resistor for current limiting. |
